English: A technician at the National Advisory Committee for Aeronautics (NACA) Lewis Flight Propulsion Laboratory examines one of the massive axial-flow compressor stages that created the high-speed air flow through the 8- by 6-Foot Supersonic Wind Tunnel. The tunnel’s first run was on April 3, 1949, just over a week before this photograph was taken. The 8- by 6 was the laboratory’s first large supersonic wind tunnel and the NACA’s largest supersonic tunnel at the time. The 8- by 6-foot tunnel was originally an open-throat non-return tunnel. The supersonic air flow was blown through the tubular facility and expelled out the other end into the atmosphere with a roar. Complaints from the local community led to the addition of a muffler at the tunnel exit in 1956 and the eventual addition of a return leg. The return leg allowed the tunnel to be operated as either an open system with large doors venting directly to the atmosphere for propulsion system tests or as a closed loop for aerodynamic tests. The air flow was generated by a large seven-stage axial-flow compressor, seen in this photograph, that was powered by three electric motors with a combined 87,000 horsepower. The system required 36,000 kilowatts of power per hour to generate wind velocities of Mach 1.5, and 72,000 kilowatts per hour for Mach 2.0. |
